12 Volt 100Ah Slimline lithium battery iTECH100SX IP67 Waterproof & 270Amp max discharge. 

The iTECH100SX 100Ah Slimline Lithium Battery has been designed and developed from the ground up to be the ultimate lithium battery for all canopy setups and Dual/Single Cab utes! Although the iTECH100SX is only 110mm wide and weighs 11.3kg, the iTECH100SX packs a serious punch for a battery of its size. 

Taking the lead in the lithium battery industry, iTechworld have enabled the iTECH100SX to have a true 100% useable capacity meaning you have access to 100Ah of lithium LiFePO4 power! In stark contrast, your old lead acid battery only gives you 50% useable capacity, meaning one iTECH100SX is equivalent to two 100Ah lead acid batteries! 

Thanks to the specifically designed internal BMS (Battery Management System), the iTECH100SX has a maximum discharge current of 270 Amps. In real-world terms, a single iTECH100SX will run a 2000W Pure Sine Wave Inverter allowing for hot coffee from a coffee machine or scrambled eggs cooked from an induction cooktop whilst off-grid. 

Utilising A-grade prismatic lithium LiFePO4 cells, the iTECH100SX offers drastic advantages over other cell types. Prismatic cells are thin in profile, deliver higher discharge, have a longer life expectancy, are extraordinarily light and utilise a more effective use of space.

Just like our flagship, the iTECH120X, the all-new iTECH100SX is IP67 Waterproof and offers extreme vibration resistance to combat corrugated roads thanks to iTechworld's exclusive vibration-dampening technology. If you mount your batteries on the exterior of your vehicle, boat or caravan, you no longer have to worry about water damage with the iTECH100SX.

Designed and developed in Australia, the new iTECH100SX Slimline Battery is suited to thrive in our tough Australian conditions. The iTECH100SX includes a five-year Australian warranty with the confidence of an Australian company backing their products.
